Application filed August 22 1903. Eerial No. 170,427. (No model.)

To (all who/1t (It HT/(by concern:

Be it known thatl, \VILLLAMJ. (JoNNnLL, a citizen of the United States,residing at Fairmont, in the county of Marion and State of WestVirginia, have invented new and useful Improvements in Attachments for Work- Benches, of which the following is a specification.

My invention relates to new and useful improvements in attachments forwork-benches, especially adapted for carpenters use; and its object isto provide a combined stop and clamp for holding the strips of wood inproper position for planing, said attachment being adjustable to adaptit for use with strips of different sizes.

A further object is to provide an attach ment which permits thebench-screw ordi narily employed to be dispensed with.

With the above and other objects in view the invention consists in thenovel construction and combination of parts hereinafter more fullydescribed and claimed, and illustrated in the accompanying drawings,showing the preferred form of my invention, and in \VlllCll Figure 1 isa plan View of the attachment. Fig. 2 is a side elevation thereof. Fig.3 is a section on line 3, Fig. 1. Fig. 4: is a perspective view of theadjustable stop-plate, and Fig. 5 is a bottom plan view of theextension.

Referring to the figures by numerals of reference, 1 is the body of thedevice, having a downward]y-projecting extension 52 having a rectangularrecess 3 in its front face, the side walls of which are grooved for thereception of beads 4., formed at the sides of a slide 5, which fitssnugly within the recess 3. A longitudinally-extending groove 6 isformed within the rear face of the slides, and secured therein is aspring-strip 7, which is adapted to bear upon the inner wall of recess 3and hold the slide 5 in any position to which it may be adjusted. Theslide has a preferably rectangular head 8, which is adapted to fitwithin a corresponding recess 9, formed within the body 1 at its forwardedge, and the rear edge of this recess is cut away, as shown at 10, soas to permit the end of a linger of the user to be placed intoengagement with the recessed inner end 11 of the head 8. The forwardedge of the head 8 is toothed or serrated, as shown at 12.

In rear of the head 8 and at opposite sides thereof are arranged earns13 and let, respectively, having pivot-pins 15, which project downwardfrom their lower faces and are held in engagement with the body 1 in anysuitable manner. One of these cams is circular in form, while the otheris in the form of a seg- 6O ment of a circle, the straight edge of whichis toothed or serrated, as shown at 16. The curved faces of the cams arepreferably milled.

The device above described is adapted to be fitted within the upper faceof a work-bench 5 and secured in position by means of screws or otherdevices inserted through apertures 17 formed within the body 1. When itis desired to work the edge of a strip of wood, it has been customary toplace it within a 7 bench-screw in order to hold it in proper position.By employing the device herein described, however, it is merelynecessary to swing the cam forward--to wit, toward the toothed edge 12of the head 8---until the space 7 5 formed between the straight edge 16and the cam 13 is suflicient to admit the strip. When the said strip ispressed forward, the cam 13 will be partly rotated automatically andwill firmly clamp the stripin position. Larger Q strips can be heldtogether by reversing the cams and using the milled faces of both ofthem for clamping upon the strip. When it is desired to use the stop, itis merely necessary to insert one finger into the recess 10, so 5 as tobring it into engagement with the inner edge 11 of the head 8. Said edgecan then be drawn upward a desired distance and will be held in adesired position by reason of the frictional contact between thespring-strip 7 and 9 the rear face of the recess 3. It will be seen thatthe device is extremely simple and inexpensive in construction and canbe readily attached to a work-bench.

In the foregoing description I have shown the preferred form of myinvention; butI do not limit myself thereto, as I am aware thatmodifications may be made therein without departing from the spirit orsacrificing any of the advantages thereof, and I therefore re- I00 servethe right to make such changes as fairly fall Within the scope of myinvention.

Having thus described the invention, What is claimed as new is 1. Anattachment for Work-benches comprising abodyplate having a recess in oneend thereof, a recessed extension depending from the plate, a slideWithin said recess, longitudinally-extending ribs upon the slideengaging the walls of the recess, a spring secured within the slide andadapted to bear upon the extension, and a toothed head on the slide andnormally seated Within the recess Within the body-plate.

2. An attachment for Work-benches comprising a body-plate having arecess in one end thereof, a recessed extension depending from theplate, a slide ithin said recess, longitudinally-extending ribs upon theslide engaging the Walls of the recess, aspring secured Within the slideand adapted to bear upon the extension, a toothed head to the slidenormally seated Within the recess in the body-plate, andoppositely-disposed cams upon the base.

3. In an attachment of the character described, the combination With abody-plate having a recess therein; of a recessed extension to saidplate, a slide adjustably mounted Within the extension, means forholding the slide in adjusted relation to the extension, a toothed headupon the slide adapted to be seated Within the recess in the body-plate,a circular cam mounted upon the body-plate, and an oppositely-disposedsegmental cam upon the plate, said last-mentioned cam having a flatserrated face.

In testimony whereof I aflix my signature in presence of two Witnesses.

IVILLIAM J. CONNELL. Witnesses N. (J. STEELE, W. H. STovER.
